Rabbit drama, need advice

Ok here is the situation:
I have 5 hens and one rabbit (female-I think mini lop) they all live in the coop and have a little fenced in yard. I just caught my do with a tiny little baby bunny (a wild one) I cant put it back in the yard because of the dogs, so i put it in the coop under the little rabbit house I have in there and put extra pine shavings. What else can I do besides this? and Is it possible that my mini lop might take care of it, or will she kill or hurt it? What does a newborn bunny eat? do they need there mothers milk? By the way my mini lop has never has bunnys of her own and she might be a he anyway (because of the way she trys to breed with my chickens
Help me Help me Help me! I want this little bunny to make it!

I found one last year and I kept it in a large tote with rabbit pellets and a water bottle. until it was 2 months old I didn't handle it much just to change out litter & take a few pictures. I then took it to hiking trail and let it go. Didn't want to keep it longer then I had to. Did find a baby squirrel and took it to the vet they take in babies to raise or will find someone who takes care of wildlife for release again.
